There were two Apple drives made without buttons, M0130, a 400k drive
and the M0131, an 800k drive. These will only work on the Mac unless
you have a rare controller card in your Apple II.

The A9M0106 has a button and will work with Mac or the IIgs or IIc+.
It'll also work with a II+ or IIe that has one of two rare controller cards.
It will not work with the IIc.

The G7287 is Apples 1.4mb drive. It has an eject button and will work
with Macs although some like the Mac plus will only use it as an 800k
drive. It will function in the IIc+ and IIgs as a 800k drive too unless you
have a Superdrive controller card that lets it use 1.4mb disks. The
SuperDrive controller card also works nicely in the II, II+, and IIe.

The 3.5" Unidisk A2M2053 has a button  but will not work with the Mac.
It will work with the IIgs although more slowly than the A9M0106. It'll
also work with some IIc, all IIc+ and any IIe or II+ with one of three
controller cards
